Cast Changes

  1. Modifies Tharros Strike with: Tharros Strike Augment: Increases Critical Damage by 100% on enemies you hit.
  2. Rank up the augment to unlock the full effect values.
  3. Costs a mod slot (and capacity) — only equip it when the change matters for your loop.

Worth the Slot?

  1. Worth it when the augment’s change is central to how you play Styanax.
  2. Skip it if the base Tharros Strike already does what you need and you’d rather keep the slot for survivability or strength.

Tips & Tricks

  • Read the battlefield first — cast Tharros Strike when it actually solves the room, not on cooldown habit.
  • Pair Tharros Strike with movement and energy economy so you’re not stranded after a big spend.
  • On Steel Path, confirm whether Tharros Strike still carries without strip, Viral, or a squad buff.
  • If you never press 2, it’s the first Helminth candidate on Styanax.

Mobile Defense / ExcavationUse Tharros Strike to control or delete the swarm on the objective, then reposition.
Exterminate / Capture Speed RunsCast Tharros Strike only when it saves time — skip it on empty tiles.

Comparisons

  • VS

    Vs similar tools on other frames — Tharros Strike is tuned for Styanax’s loop — don’t judge it as a standalone subsume without the rest of the kit.
